Vista - Custom TSP problem on Windows Vista 32 bit

Hello,

I have an issue with a custom TSP written in C++. It should be used by outlook to make a call. It works fine under windows xp, but under Vista it doesn't. I am not sure which is the problem because I am able to add it in the Advanced tab from Phone and Modem options and I am able to select it from the New Call dialog from Outlook to use it as a line. When I press Start call i receive an error "An internal error occurred in the automatic phone dialer. Close the dial phone box and then open it again".
Also, using the dialer.exe application from microsoft I am unable to use it. The following error shows: "An internal error occured in Phone Dialer. Quit and restart Phone Dialer."
Can you please advice me how I can solve this?

Thanks,
Gabi

Hi Gabi,

Outlook is no longer included with Vista and I suspect your C++ application is using the wrong dialer calls for standard users and either requires elevation or a slight rewrite to work without an existing elevated Mail or Dialer Client running.

Hi Steven,

Thanks for your reply.. I am using Outlook 2003 and I have disabled the User Access Control. Is there anything else you think I can disable? I also suspect is something caused by permissions issues...

I read on the internet that the outlook feature of making calls uses the dialer.exe from windows/system32 which is included in Vista. What do you suggest?

Thanks,

Gabi

Hi Gabi,

If disabling UAC didnt solve the dialer issue I dont think theres much you can do without getting the application rewirtten for the new COM objects and calls found in Vista (dont forget to turn UAC back on too )

Hi Steven,

Rewriting the application is not a problem, even it's not me who wrote this TSP.. I don't have so much experience in writing app for windows, especially windows Vista but I am willing to learn. Can you point me where I can find some information about COM objects and calls found in Vista ...

Thank you again,
Gabi

Hi Gabi,

Im not very experienced with COM objects (OLE, ActiveX, Com+, DCOM)

You can find information about them here with examples and calls

Microsoft Dynamics AX System Classes

Hello Steven,

I solved my problem, the problem was with the Telephony Service from Windows Vista.

Thanks for your help and interest,
